Patent number: 10110353Abstract: Various methods and systems are provided for allocating time-frequency resources for downlink (DL) and uplink (UL) communications between base stations and mobile stations. Different forms of resource allocation messages including combinations of bitmaps and bitfields provide additional information about the resources and/or how they are assigned. In some implementations the resource allocation messages enable reduced overhead, which may ultimately improve transmission rates and/or the quality of transmissions.Type: GrantFiled: March 30, 2017Date of Patent: October 23, 2018Assignee: Apple Inc.Inventors: Robert Novak, Mo-Han Fong, Hang Zhang, Sophie Vrzic

Patent number: 10110354Abstract: Methods and systems are described that are suitable for channelization, in particular, but not limited to, the IEEE 80216.m telecommunications standard. For a time-frequency resource, physical sub-carriers for each of one or more zones in the time-frequency resource are assigned to one or more zones having a respective type of transmission. At least one zone is allocated for a type of transmission using localized sub-carriers. The physical sub-carriers assigned to each zone are permuted to map to logical sub-carriers. Groups of resource blocks are formed, in which each resource block includes at least one logical sub-carrier for each of the one or more zones. The information defining the groups of resource blocks for each of the one or more zones can then be transmitted to a user. The information may be in the form of a zone configuration index.Type: GrantFiled: May 23, 2017Date of Patent: October 23, 2018Assignee: Apple Inc.Inventors: Sophie Vrzic, Dong-Sheng Yu, Mo-Han Fong

Patent number: 10028168Abstract: A method and system for supporting operation of a scheduler by providing indications of communication device transmit buffer status is provided. The indication of buffer status can be generated by a third-party device which is external to both the communication device and the scheduler. In some embodiments matched local and remote models of the buffer are maintained at the communication device and third-party device (or scheduler), respectively. The communication device monitors locally for drift of the model from the actual buffer status. When a level of mismatch in the model is detected, both the local and remote models are updated to mitigate the mismatch.Type: GrantFiled: December 8, 2015Date of Patent: July 17, 2018Assignee: Huawei Technologies Co., Ltd.Inventors: Aaron James Callard, Sophie Vrzic, Philippe Leroux

Patent number: 9974060Abstract: Methods, base stations and access terminals for uplink signalling are provided. Resource request channel characteristics such as location in time-frequency, sequence, time slot, are assigned to each access terminal to distinguish their resource requests from the resource requests of other access terminals. Access terminals make requests using a resource request on a resource request channel having the assigned characteristics. The base station can then determine which access terminal transmitted the resource request based on the resource request channel characteristics of the resource request channel upon which the resource request was received. The base station then transmits a response to the request which may for example be a new resource allocation, a default allocation or a renewal of a previous allocation.Type: GrantFiled: September 11, 2008Date of Patent: May 15, 2018Assignee: Apple Inc.Inventors: Robert Novak, Mo-Han Fong, Sophie Vrzic, Jun Yuan, Dong-Sheng Yu, Jianglei Ma
